title: The efficacy and safety of simultaneous transurethral GreenLight photoselective vaporization of bladder tumor and prostate in patients with bladder tumor and lower urinary tract symptoms.
abstract: OBJECTIVE
  We compared the safety and efficacy of simultaneous transurethral GreenLight photoselective vaporization of bladder tumor and prostate (PVBT/PVP) in patients with bladder tumor and bladder outlet obstruction caused by benign prostate hyperplasia (BPH).
  
  
  METHODS
  Sixty-two patients with bladder tumor were enrolled in our prospective and randomized trial. A total of 37 men underwent simultaneous transurethral PVBT/PVP, and 25 patients underwent PVBT alone. The clinicopathological parameters and the recurrence of bladder tumor on the bladder neck/prostatic fossa were evaluated in all patients.
  
  
  RESULTS
  Clinicopathological parameters of both groups were similar. The rates of recurrence, progression and tumor recurrence of bladder neck/prostatic fossa were 16.0, 4.0 and 4.0 % in the simultaneous resection group, and 18.9, 5.4 and 8.1 % in the group PVBT, respectively. No statistically significant differences were found between the two groups (P > 0.05).
  
  
  CONCLUSIONS
  Simultaneous PVBT/PVP may help decrease the overall recurrence rate and tumor recurrence in bladder neck/prostatic fossa. PVBT/PVP can be performed effectively and safely in patients with bladder tumor and BPH.
